Arbor Networks – Why Work For Us?


A Research-Driven Approach to Addressing Global Network Challenges

A global leader in network security. A hub for Internet-wide research. An exciting place to work.
Arbor was founded out of groundbreaking research conducted at the University of Michigan. This research was eventually funded by the U.S. Defense Agency Research Projects Administration (DARPA).  Out of that research, Arbor Networks was created in 2000.

Since then, Arbor has focused exclusively on researching, detecting and mitigating network-based threats. The company is best known for its pervasive footprint in service provider networks. Arbor technology is deployed in 70% of service provider networks globally, including 90% of tier one operators. Arbor technology is also broadly deployed among the largest hosting and cloud providers.

Less well understood is the fact that Arbor has been working with the world’s leading enterprise network operators since 2003, counting more than 150 leading financial services, retail, social media and healthcare brands, as well as universities and government organizations, as customers.

The ATLAS Advantage
What separates Arbor from other security vendors is how we leverage our service provider footprint to benefit all of our customers.  Arbor created ATLAS, a collaborative project with more than 300+ service providers who have agreed to share anonymous Internet traffic data with Arbor’s Security Engineering & Response Team -- ASERT. This data, totaling 90Tbps, is enhanced by Arbor’s global honeypot network of 45+ sensors in the dark, unused address space of provider customer networks. That information is aggregated, analyzed by our ASERT team and fed back to our customers in the form of attack signatures, via our product deployments.  From this unique vantage point, Arbor is ideally positioned to deliver intelligence about DDoS, malware, botnets, exploits and phishing attacks that threaten Internet infrastructure and services today. Ultimately, ATLAS gives Arbor customers a considerable competitive advantage by giving them both a micro view of their own network combined with a macro view of global Internet traffic; this is a powerful combination of network security intelligence that is unrivaled today.

Industry Thought Leadership
With the unique visibility provided by ATLAS, Arbor security researchers are sought out for their insight and analysis of critical security and infrastructure issues such as denial-of-service (DoS) attacks, Domain Name System (DNS) security and the adoption of IPv6, as well as global Internet events. Arbor has been invited to testify before the House of Lords on behalf of the European Union on the subject of “Protecting Europe Against Large-Scale Cyber-Attacks” and has briefed NATO and many other international organizations and governments around the world on network infrastructure and security vulnerabilities.

Arbor’s long-standing relationships and reputation as a trusted advisor and solution provider make the annual Worldwide Infrastructure Security Report possible. This report offers a rare view into the challenges of network operators on the front lines of a global battle against botnets and DDoS attacks.

Always Innovating, Always Moving Forward
Since its founding, Arbor has been working with the world’s most demanding network operators to help them understand, identify and mitigate network-based threats to their businesses. We’ve seen the evolution in attack trends and techniques and we’re constantly innovating in the area of product development, as well as our research capabilities, to stay on the very leading edge of cyber security today.

Just this year, Arbor was named one of the top ten most brilliant DARPA inventions of all time – alongside the Internet itself, Google Maps and GPS. This honor speaks to our deeply rooted focus on constant innovation and technology advancement.

The Internet plays such a central role in business, in government and in society today, securing the online world is more important than ever. The stakes are high. The challenges are great. And Arbor is armed and ready with great technology, great people and an energetic culture of innovation. That’s what makes Arbor Networks such a great place to work. 

Corporate Operations
Headquartered in the United States, Arbor Networks operates out of Burlington, MA, with R&D facilities in Ann Arbor, MI, and Atlanta, GA. Our Europe, Middle East, and Africa (EMEA) operations are based in London, while our Asia operations are based in Singapore.

A fun place to work. A great place to grow.

Arbor Networks was founded in 2000 out of research that originated at the University of Michigan and was subsequently supported by the U.S. government’s Defense Advanced Research Projects Agency (DARPA). Today, we're a leading provider of network security and management solutions for many of the world’s largest and most complex Internet service providers, enterprises and government organizations.

The spirit of innovation and collaboration that made our original research possible remains a cornerstone of our corporate culture. Arbor hires highly talented and deeply committed employees, and we recognize and reward them for what they bring to our company.

Arbor Networks has collaborated with Google Ideas to create a data visualization that shows what a global problem distributed denial of service (DDoS) attacks have become.

The data is updated daily, and historical data can be viewed for all countries.

    Great colleagues, fun environment with many opportunities to learn new things. Employee benefits are great, free snack wall and soda machines. Fun company events. Great work/life balance.


    Since the Netscout acquisition, the quality of working at Arbor has gone down due to their meddling. Engineering morale is constantly going down because promotions and raises have been withheld multiple times since the acquisition, feels like we are punished for not hitting higher sales numbers than the past year in which we had phenomenal sales in a market we've already saturated and currently dominate. I'd love to return to Arbor were it not for Netscout.

    Senior SQA Engineer Interview

    Anonymous Interview Candidate in Burlington, MA
    No Offer
    Neutral Experience
    Average Interview


    I applied through an employee referral. I interviewed at Arbor Networks (Burlington, MA) in June 2017.


    Applied through an internal referral, got email from recruiter to schedule phone screen after about 1.5 week, had 1 hr phone screen with hiring manager, it was all technical questions, after another week after phone screen, recruiter contacted me to schedule on-site interview, this on-site interview was kept being rescheduled multiple times with various reason(manager not available, team not available etc etc), after another 3 weeks, finally went in for on-site interview. It was 3 sessions interview, 2 technical sessions of 45-minutes each with 2 engineers (2 engineers local, another 2 engineers from MI), of course those two sessions were all technical non-stop. The third session was with a project manager and hiring manager, was more on behavior type of questions and Agile. Personally think the interview went well, and recruiter said there was no negative feedback on me, yet, there was no offer, just like most people left review for this company, I do not think they are seriously or determined to hire, I think they just look around in market, or something like that, before my own interview, I had read all the reviews on glassdoor for this company, I had feeling that I would have similar experience like everyone else, sure that was what happened.

    Interview Questions

    • technical were all networking protocols you list, database/SQL, test design, test automation
      behavioral ones were typical ones such as why this place, what you see yourself in 3-5 years, why we should hire you, the project manager was more on Agile.   Answer Question
